Myr invention relates to loom harness, and itrelates more particularly to the construction `and) arrangement ot the heddles in the heddlei'ranjies tor controllingy the warp ends for the purpose ot forming successive sheds ot the warp duringl the operationy ot the loom.'y

Theobject oil my invention is to provide an improved form of construction and arr rangement of `the heddles in ,the heddley 'frames which is particularly yadaptable tor fever, lind its greatest usefulness in connec-k close iii'istallations for weaving;` 'tine yfabrics, and whereby the warp ends controlled by ad-` iacent Jframes will more treely pass tlie'clyes 'otthe heddles during the reeiprocation of the trames for the purpose of 'forming the sheds. thereby minimizing, to a `large extent, breakage of the warp ends. l i

llVhile `it should be understoodfthatthe underlyingprinciple ot my present inven` tiony may bek used in connection with vari v`oi'istypes of heddles, the invention will, howtionwith that type of metallic heddles as distinguished 'from cotton or thread harness whichare formed from thintlat strips oit rmetal kor wire, having` the warp eyes formed in the central portions thereof by slitting the metal of the` strip and expandingthe same to 'term the eye through which the warp endy passes. f

Hereto'tore,

age ot thewarp ends occurs by reason ot the resistance which occurs during;r` the reciprocation of thewvariousy heddle ytranne-s inthe threads controlled by one of the Jframes passes the warp eyes of the heddles mounted Lin another ot the heddle iframes,thisoccur ringparticularly in the ,weavingg'ol ytine tabries where the installation ot the heddles 1n the trames is close, and where the'warp is necessarily line, and theretore more easily f broken. n l' v n ,f

To overcome they above mentioned u difficulty, in some instances there were provided a plurality oit sets of heddle trames, each set being' operated in unisonto control. oneset of the ,warp ends, which was a more or less clumsy expedient, and which led to thesublsequent development o'l the mounting` Lot a plurality of sets of heddles ina single trame,

vertical planes.

it has been recognized by those understood fromv the 'following description,

" skilled inthe art that a great deal yot break- `veloped comprised the provision of hcddles ott-,set out oit the plane of the supporting bars, and arranged with the ott-set portions alternatively to one side and another, so as f to cause the warp eyes to lie 4in separated y n These expedients, however, have been found insufficient to fullyk accompl ish the desired purpose, particularly for weaving` line fabrics, and my present invention contemplates a still further advance in the art, as will be hereinafter more fully set forth. f

Yhile there is shown and described in the present application one species of my pres-k enty invention, and the same isherein shown as embodied in various modifications of said species, I have also shown and described in a companion application, tiled herewith, another species and the rmanner of embodying the same in various modifications thereof. It shonld, however, be understood that ymy invention is susceptible of embodiment in a variety of other species and modifications thereof, as Lwillbe readily apparent to those skilled in the art upon a proper understanding ol the 'underlying principle of my present invention. i f i Thenature and characteristic features of myk present invent-ion will be more readily ranged in suchk manner as to embody the `main Vfeatures ofk my rpresent invention, mounted therein; v v Fig. 2 is a vertical sectional view thereof;

f 3 is a sectional view, similar to Fig. 2, butshmving armoditied form of construction `and arrangel'nent of the heddles;

Fig. 4 is afragmentary elevational Viewk illustrating the arrangement of the heddlesy shown in F 3; and f Fig. 5 is a sectional view, similar to'Figs. 2 and 3, but showingr another modified form ot yconstruction yand arrangement of the Lh'eddles- Referring to the drawings, the heddle trame there shown consists of the top and ybottom bars 6, connected at their ends by sok y means ot the side strips 7. Extending from end to end ot the heddle traine, and arranged near the top and bottoni bars 6 in the usual manner, are the heddle bars 8 upon which the heddles are mounted.

Y Reterring'now more particularly to Figs.

1 aiil of' the drawings, the heddles whichY are mounted upon and supported by the bais 8'k are provided in two sets, 9 and 10, respec-V tively. The heddles 9 and 10 ot' each set are provided with warp controlling eyes in the central portions thereof, which warp eyes may be ot any preferred conformation. rEhe 1 relative location oiY the warp'eyes 11 ot the heddles9 with respect to the warp eyes 12' of the heddles 10, when the same are mounted in the ftraine, is an important feature ot the presentinvention.V `rlhe warp eyes V11 ot' the heddle's 9 'are longitudinally located` therein, vand thelwaip eyes 12 of the h eddles l0 -are longitudinally located therein, at

suehpositions, respectively, that the warp Veyes ot' the set of lieddles 9 will lie ina horizontal plane diiiiereiit troni that ot' the warp eyes 12 oi the setot' lieddles 10.

The lieddles are mounted upon the suppoitiiig bars by tirst placing thereon a heddle 9 otfoiie set, then a heddle '10 et the a other set, then another heddle 9 oft' the iirst mentioned set, then another lieddle 10 ot' the otherset, and so onaltei'nately throughout the trame. f

In the niodiiication ot the invent-ion shown in Figs. 3 and tot the drawings, there are providedtwo pairs ot' sets of heddles, making in all tourA sets of lieddles diiierent-ly arranged as'tov the positions ot' their respective warpy eyes, and preferably arranged in se-k ries ot one ot each set.

Figs. 3 and el), the warp eyes 210i the hedf dles 15 are longitudinally located upon thev heddles 15 Yat such position thatV all` ot the warp eyes ot the set ot' heddles 15 will lie in a horizontal plane'diilerent t'romthat of the warp eyes 22 ofthe set ot heddles 1G, and likewise the warp eyes 23 ot the set ot heddles 18 are longitudinally located upon the heddles 18 at such position lthat all ot'i saidwarp eyes 23 ot the set ot heddles 18 will lie in a horizontal plane diii'erent t'rom that ofthe warpeyes 24 ot the set ot lieddles 19. By this arrangement, the heddles will be preferably mounted upon-the supporting bars by iirst'placing thereon a heddle 15 oi" `one'set, then a heddle lbkof another set, then another embodiment of the invention, wheref iii the use'ot ott-set'heddles iii*L be dispensed with, and which is particule" y adaptable to extremely close installations. ln this instance there are provided, at the top and bottoni ot' the trame, two or more ot the lieddle supporting bars S, and the heddles in this torni of the invention may be substantially straight throughout their longitudinal extent, similar to those illustrated in Figs. 1 and 2 of the drawings, there being n'iouiited, on each pair ot the supporting bars 8, he ldlesf9 and 10 in which the eyes 11 and thereof, respectively, will be located alternately above and below each other.

it will be seenthat-iii each ot the toreg'oinO arrangements there is provided, in a single harness traine, a plurality of sets of lieddles, the warp eyes ot each set of which Y will lie iii. diilei'ent horizontal planes, and by this arrangement, as the trames are reciprocated during the operation otl the loom.

a greater tree-doin tor thepassage ot the` warp ends, controlled by the adjacent frames, will be ailforded, in that the warp eyes being located in a plurality ot dilierent horizontal planes, resistance 'to the pascageoic the warp ends, which are controlled by the other trames, will Vbe greatly minimized, and in this manner breakage oi' the warp ends, due

to the strain which ordinarily occurs at this point, will be reduced to amiiiinimii.

lt should also be understood that the various torins illustrated are, to a certain extent, sugfrestive merely, and that a variety ot' other forms or embodiments ot the in* vention will readily occur to those skilled in the art.

Having thus described the nature and cl iiaeterislic Vfeatures of my invention, what. I claim as new and desire to secure by Letters rPatent ist 1. ln a loom harness, a harness trame, heddle supportingbars carried thereby, and a 'L' l n individual heddles formed or thin flat metal or wire mounted upon said supporting bars in a plurality ot sets, the hcddles ot on 1 having warp controlling eyes at certain longitudinal locations and the heddles ot an-V other set having warp controlling eyes at different longitudinal locations, whereby the warp controlling oyes oit oneset ot licddles are in one horizontal plane and the warp controlling eyeso'l1 another set are in another rhorizontal plane, and the eyeportions of one ot said sets ot heddles being in the saine vertical plane as the eye portions of another set otheddles.
